What is u velocity when v velocity is acceleration?

'v' generally refers to final velocity. 'u' generally refers to initial velocity (because not everything starts from a motionless state, where 'u' would equal zero). It is better to annotate initial velocity as v 0 (v-sub-zero or simply v-zero).

What is acceleration and velocity?

Acceleration and velocity Velocity - which is not quite the same thing as speed -- is the measure of the rate of change in position. In other words, to calculate velocity, we divide the change in an object's displacement -- how far it moved -- by the time it took to move. If an object moves, say, ( Full Answer )

Velocity and Acceleration?

velocity is the rate of change of displacement with respect to time where as acceleration is the rate of change of velocity with respect o tome.

Is velocity and acceleration the same thing?

Velocity is defined by physicists as both speed and direction, that is to say, if you are moving at 30 feet per second in a northerly direction, that is a velocity. Acceleration means a change in velocity. Physicists consider speeding up, slowing down, or changing direction all to be forms of accele ( Full Answer )

What makes velocity different from acceleration?

Acceleration is the change of speed upward. Velocity is any speed, in a fixed direction. So the diference, is that in speed; the direction can change, but the speed remain constant. Only if it moves faster or slower dose the speed change. So in velocity, if the speed, or the direction change, th ( Full Answer )

How is speed velocity and acceleration related?

Speed is the rate of motion usually expressed as distance traveled per unit of time. . Velocity is the rate of change of position. Both speed and direction are required.. Acceleration is the rate of change in velocity. In common speech, acceleration is only for an increase in speed; a decrease ( Full Answer )

Can a body have velocity without acceleration?

Yes. Velocity is speed per unit of time with a direction vector telling you which way the object in question is moving. Acceleration is a change in velocity - in any part of velocity. If something like, say, a rock is in deep space (a zillion light years from anything) and it's moving along unaffect ( Full Answer )

What is Velocity and Acceleration?

Velocity is the speed of an object in any given direction (constant); acceleration measures the change in speed of an object over time.

What does acceleration do to velocity?

Acceleration increases the velocity. There are two physics formulas that you can use to see more how they interact. The first is a formula for determining your current velocity at a given moment t, knowing your initial velocity and your current acceleration. v = v0 + at (v0 is v-naught. The ( Full Answer )

How are speed velocity and acceleration different?

Velocity is a vector, meaning that it has a direction. When it is being expressed, the direction is given with it (e.g. 5m/s NW). Speed is a scalar, not a vector, so it doesn't have a direction connected with it. Thus, when it is expressed, the direction variable is omitted (e.g. 5m/s). Accele ( Full Answer )

How do acceleration and velocity relate?

Acceleration is the rate of change of velocity over time. One formula that shows this relationship is: v f =v i +at where: . v f = final velocity . v i = initial velocity . a = acceleration . t = time

How is velocity different from acceleration?

Velocity is the speed of an object in a given direction . So if a vehicle is travelling down a street at 30 miles per hour both its speed and velocity is 30 miles per hour. However, if it turns round and travels back at 30 miles per hour its speed is the same, but its velocity is now in the ( Full Answer )

How does acceleration affect speed and velocity?

Acceleration changes the speed - usually increases it. A reduction is speed is negative acceleration , or deceleration. Acceleration can change the speed or direction (or both) of velocity.

Is it possible to have an acceleration with constant velocity?

No, the definition of acceleration is the increase change in velocity over time. An acceleration can also be a decrease in velocity over time. Constant velocity refers to an object that maintains the same velocity as time progresses. If the object has an acceleration, its velocity will not remain ( Full Answer )

Are velocity and acceleration the same?

Velocity or speed is the rate of motion across a distance, while acceleration is the rate of change in velocity, i.e. speeding up (or in deceleration, slowing down).

What is the acceleration if the velocity is 0?

It's not possible to tell from only that much information. When you throw a rock up, its acceleration is the acceleration ofgravity from the moment it leaves your hand until it hits the ground. But itsvelocity is upward some time, downward some time, and zero at the top.

How is velocity and acceleration the same?

They are not the same. Velocity is the displacement (change in location) over time and acceleration is the change in velocity over time.

Examples where velocity is zero but not acceleration?

When a ball is thrown up in the air there is a moment, when the ball reaches its maximum height, the velocity of the ball is zero, and acceleration due to gravity still exists [downwards]. If the velocity is zero, the acceleration is not necessarily zero. .

Why are velocity and acceleration both rates?

Its to do with constant values, the rate of acceleration refers to a constant change of velocity over time, so an acceleration of 10 (m/s)/s is a constant increase of velocity per unit time ( increase of 10 metres per second, every second ) Velocity is a constant increase in distance, per unit tim ( Full Answer )

Does velocity equal acceleration?

No. If they were the same thing, there would be no need to invent two different names for it. Acceleration is the rate at which velocity changes.

What are acceleration and velocity?

'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.

What happens to the velocity when an object is accelerated?

A moving object being accelerated will show a change in its velocity (it may move faster, or slower, or experience a change in direction). A stationary object will respond to acceleration only if there is no other force acting to prevent its response. For example: gravity is a constant force of acc ( Full Answer )

What is the link between velocity and acceleration?

I'm not quite sure what you're asking, but..... An object that is accelerating simply means that that object's velocity is changing . It can be increasing (positive accel.) or decreasing (negative accel.). If the acceleration is zero, that means the velocity is constant. (Keep in mind that thes ( Full Answer )

When velocity increases does acceleration increase?

No. Acceleration IS a change of velocity - any change. When velocity increases, there IS acceleration. The acceleration itself may be increasing, decreasing, or remain constant.

Why is acceleration zero with uniform velocity?

Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.

What potential difference must be applied to produce an electric field that can accelerate an electron to a velocity of 10 raised to 7 meters per second?

An electron, being a charged body, is acted on by a force, and is therefore accelerated, when immersed in an electric field. If you really want to be cruel, you attach numbers to the whole situation and hand it to someone to solve. The kinetic energy of a moving electron is KE = (Lorentz f ( Full Answer )

What is acceleration velocity and speed?

Speed is (distance covered) divided by(time taken to cover the distance). Velocity is a speed and its direction. Acceleration is any change of velocity.

When can both velocity and acceleration be negative?

Both velocity and acceleration can be negative when an object is slowing down, or when an object accelerates backwards, which is a negative direction, such as a car backing out of a driveway.

Does velocity change while accelerating?

Yes, that's the whole idea of acceleration. To be precise, acceleration is defined as the rate of change of velocity - how fast velocity changes. In symbols: a = dv/dt
